TriAusMin Ltd. announced on July 10 that it received final project approvals from the New South Wales Department of Planning and Infrastructure for its Woodlawn retreatment and underground projects. The projects are located at the site of the former Woodlawn mine, which was operated, first as an open-pit and then as an underground mine, from 1978 to 1998. During that time, the mine produced 13.8 million mt of ore grading 9.1% zinc, 3.6% lead, 1.6% copper, 74 g/mt silver, and 0.52 g/mt gold.

TriAusMin’s project involves retreatment of more than 10 million mt of tailings that were deposited in three dams at the Woodlawn mine. The underground mine project is targeting an initial mine life of eight years at a production rate of 300,000 to 400,000 mt/y.

The Woodlawn site is located near Tarago, New South Wales, about 200 km southwest of Sydney.
